NOTElWhen DSC is on and you attempt to free the
vehicle when it is stuck, or drive it out of
freshly fallen snow, the TCS (part of the
DSC system) will activate. Depressing the
accelerator will not increase engine power
and freeing the vehicle may be difficult.
When this happens, turn off the TCS/DSC.
lIf the TCS/DSC is off when the engine is
turned off, it automatically activates when
the ignition is switched ON.
lLeaving the TCS/DSC on will provide the
best stability. When the TCS/DSC is off, the
TCS/DSC does not activate but the brake
LSD (Limited Slip Differentials) function
remains.
lIf the DSC OFF switch is pressed and held
for a second or more, the TCS/DSC system
may become inoperative due to the system
detecting a switch problem. If the TCS/DSC
system becomes inoperative, the TCS/DSC
and the DSC OFF indicator lights
illuminate simultaneously. In this case, turn
off the engine and restart it to restore the
TCS/DSC.
lThe DSC only operates when the brake
pedal is depressed while driving and it is
determined that operation of the DSC is
required, even if the DSC OFF indicator
light illuminates by pressing the DSC OFF
switch.

After rotation, inflate all tire pressures to
specification (page 10-7) and inspect the
lug nuts for tightness.
CAUTION
Rotate unidirectional tires and radial
tires that have an asymmetrical tread
pattern or studs only from front to
rear, not from side to side. Tire
performance will be reduced if
rotated from side to side.
CAUTION
Limited-Slip Differential system;
don't use the following:
ØTires not of the designated size
Ø Tires of different sizes or types at
the same time
Ø Tires not sufficiently inflated
If these instructions aren't followed,
the rotation of the left and right
wheels will be different and will thus
apply a constant load on the limited-
slip differential.
This will cause a malfunction.
q Replacing a Tire
WARNING
Always use tires that are in good
condition:
Driving with worn tires is dangerous.
Reduced braking, steering, and
traction could result in an accident.
Replace all four tires at the same time: Replacing just one tire is dangerous.
It could cause poor handling and
poor braking resulting in loss of
vehicle control. Mazda strongly
recommends that you replace all four
tires at the same time.
CAUTION
(With Tire Pressure Monitoring
System)
When replacing/repairing the tires or
wheels or both, have the work done
by an Authorized Mazda Dealer, or
the tire pressure sensors may be
damaged.
NOTE
(With Tire Pressure Monitoring System)lWhen tires with steel wire reinforcement in
the sidewalls are used, the system may not
function correctly even with a genuine
wheel.
Refer to System Error Activation on page
5-34.
lBe sure to install the tire pressure sensors
whenever tires or wheels are replaced.
Refer to Tires and Wheels on page 5-34.
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tire when this happens.
New tread Tread wear indicator
Worn tread
You should replace the tire before the
band crosses the entire tread.

NOTE
Tires degrade over time, even when they are
not being used on the road. It is recommended
that tires generally be replaced when they are
6 years or older. Heat caused by hot climates
or frequent high loading conditions can
accelerate the aging process. The period in
which the tire was manufactured (both week
and year) is indicated by a 4-digit number.
Refer to Tire Labeling on page 9-23.
qReplacing a Wheel
WARNING
Always use wheels of the correct size
on your vehicle:
Using a wrong-sized wheel is
dangerous. Braking and handling
could be affected, leading to loss of
control and an accident.
CAUTION
ØA wrong-sized wheel may
adversely affect:
ØTire fit
ØWheel and bearing life
ØGround clearance
ØSnow-chain clearance
ØSpeedometer calibration
ØHeadlight aim
ØBumper height
ØTire Pressure Monitoring
System
ØLimited-Slip Differential System
Ø (With Tire Pressure Monitoring
System)
ØWhen replacing/repairing the
tires or wheels or both, have the
work done by an Authorized
Mazda Dealer, or the tire
pressure sensors may be
damaged.
ØThe wheels equipped on your
Mazda are specially designed
for installation of the tire
pressure sensors. Do not use
non-genuine wheels, otherwise
it may not be possible to install
the tire pressure sensors.
NOTE
Be sure to install the tire pressure sensors
whenever tires or wheels are replaced. Refer to
Tires and Wheels on page 5-34.
When replacing a wheel, make sure the
new one is the same as the original factory
wheel in diameter, rim width, and offset
(inset/outset).
